Joe Biden references President Trump at least 76 times in his prepared remarks for a Davenport, Iowa appearance on Tuesday — the same day that Trump will make an appearance.

Why it matters: Trump's aides have long seen the former vice president as his biggest potential threat in 2020. The president has recently been saying it out loud— and Biden seems to be just as focused on Trump — as their dueling Iowa trips provide a juicy splitscreen.

What Biden will say: "Trump doesn’t get the basics. He thinks his tariffs are being paid by China. ... The cashiers at Target see what’s going on — they know more about economics than Trump."

  • "I believe Trump is an existential threat to America."
  • "We choose hope over fear. Unity over division. Truth over lies. And science over fiction."

Why it matters: States are being asked to pitch in $100 per unemployed resident, but it’s a heavy lift for cash-strapped states that are still unclear about the details and may not opt-in at all. It leaves the states and jobless residents in a state of limbo.

President Trump, like some of his predecessors, is branding NASA's recent wins as political, presidential accomplishments even though they are the result of efforts that span administrations.

Why it matters: Experts warn that partisan politicking with NASA can lead to whiplash that leaves the agency scrambling to chase new goals whenever a new administration arrives in Washington.
